Filter

Security checks for vulnerabilities and agentic risk

Overview

This skill locally saves user-created filter rules in a disclosed OpenClaw rules file and does not show hidden, network, credential, destructive, or automatic persistence behavior.

Install this if you want reusable local filter rules. Review the saved rules periodically and avoid storing secrets, private account details, or sensitive personal information in rule criteria because the rules file is meant to persist across OpenClaw sessions.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

MCP Least Privilege
Confidence
90% confidence
Finding
The skill declares a required writable local config path and is described as creating and storing reusable rules locally, but it does not declare any explicit tool scope or permissions boundary for the implied file read/write behavior. This can lead to overbroad file access at runtime, making it harder to constrain the skill to only the intended rules file and increasing the risk of unintended local data access or modification.

Confidence
81% confidence
Finding
The skill is explicitly designed to create and manage reusable rules and persist them in a local workspace file, which introduces session persistence. Persistent state can retain sensitive filtering criteria, task metadata, or user-derived rules across runs, creating privacy and integrity risks if the stored data is accessed, poisoned, or reused unexpectedly in later workflows.

Confidence
60% confidence
Finding
Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
